Why You’ll Love This Recipe

• Bakery-Style Domes: Starting the bake at a high temperature (425°F) before lowering the heat gives the leavening agents an immediate boost, creating those tall, rounded muffin tops.   

• Wholesome & High-Protein: Fresh-milled hard white wheat brings whole-grain fiber and nutty depth, while plain Greek yogurt keeps the crumb tender and adds a boost of protein.   

• Zero Refined Sugar: Granulated monkfruit provides clean, balanced sweetness in both the batter and the crunchy streusel topping.   

• Great Way to Use Sourdough Discard: Uses up ¾ cup (180g) of sourdough discard while adding subtle complexity to the batter.

Step-by-Step Instructions

Step 1: Prep the Oven & Pan

Preheat your oven to 425°F (218°C) and line or grease a standard 12-cup muffin tin.   

Step 2: Whisk the Dry Ingredients

In a medium mixing bowl, whisk together the fresh-milled hard white wheat flour, baking powder, ground cinnamon, and fine sea salt until evenly combined. Set aside.   

Step 3: Cream Butter & Monkfruit

In a large mixing bowl—or using a hand mixer—cream together the softened butter and granulated monkfruit until smooth and cohesive.   

Step 4: Mix in the Wet Ingredients

Add the large egg, sourdough discard, vanilla extract, and plain Greek yogurt to the creamed butter mixture. Mix well until completely smooth.   

Step 5: Combine Batter & Fold in Blueberries

Add the dry flour mixture into the wet ingredients and mix just until combined—be careful not to overmix, as doing so can make whole-wheat muffins dense. Gently fold in the frozen blueberries until evenly distributed.   

Blueberry Baker's Tip: Keep your blueberries frozen right up until the moment you fold them into the batter! Using frozen berries straight from the freezer prevents them from bleeding purple streaks throughout your batter and helps them hold their shape while baking.

Step 6: Portion the Batter

Divide the muffin batter evenly into the 12 prepared muffin wells.   

Step 7: Add the Cinnamon Streusel Topping

In a small bowl, mix the streusel topping ingredients (fresh-milled flour, granulated monkfruit, softened butter, cinnamon, and sea salt) with a fork or your fingertips until crumbly. Distribute the crumble evenly over the 12 muffins—do not press it down, just lay it loosely on top so it bakes up light and crisp.   

Step 8: Two-Temperature Bake

Bake at 425°F (218°C) for 5 minutes, then lower the oven temperature to 350°F (177°C) (without opening the oven door!) and bake for 15 more minutes, or until a toothpick inserted into the center of a muffin comes out clean.   

Allow the muffins to cool in the pan for 5–10 minutes before transferring to a wire rack to cool completely. Store in an airtight container at room temperature for up to 3 days, or refrigerate/freeze for longer freshness!
